Device and method for rapid treatment of kitchen waste wastewater

Abstract

The invention discloses a device for rapidly treating kitchen waste wastewater. The device mainly comprises a cavitation air floatation device, a first-stage turbulent flow nano-aeration backwash filter, a bio-membrane reactor, a flocculation tank, a second-stage turbulent flow nano-aeration backwash filter and a girt chamber. The invention also discloses a method for treating kitchen waste wastewater by using the device. The problems of high kitchen waste wastewater output, high treatment difficulty and long reaction period are effectively solved by mainly using a mechanical method and accessorily using a biological method according to the concept that the kitchen waste wastewater is rapidly treated, the wastewater treatment time is shortened, the generated wastewater can be rapidly discharged up to the standard, and the aims of reduction, harmlessness and recycling of the kitchen waste wastewater are realized.

Description

technical field

[0001] The invention relates to a fast processing device for kitchen garbage waste water.

[0002] The present invention also relates to a method for rapidly treating kitchen waste wastewater by using the above-mentioned device, in particular to a method for removing pollutants (such as organic matter, oil, suspended matter, colloids, heavy metals, etc.) in kitchen waste wastewater. Background technique

[0003] During the collection, transportation, stacking and treatment of food waste, a large amount of pollutants are produced, such as odorous pollutant H 2 S, NH 3 and food waste leachate. Among them, the treatment of kitchen waste leachate has become a major problem.

[0004] During the stacking and landfilling of food waste, due to biochemical degradation such as compaction and fermentation, and at the same time, a liquid with a high concentration of organic or inorganic components is produced under the seepage of precipitation and groundwater, which w...
